To document the effect of orthopedic therapy on the metabolism of rats. Exerting backwards force on rats mandible and measuring concentration of rats' blood cAMP in three groups with radio-immunity. Drawing the time-concentration curve and making cosine analysis. In natural state, there was a diel rhythm change of concentration of cAMP in rats' blood(P<0.05); After being imposed orthopedic forces to inhibit mandibular growth, the normal diel rhythm of cAMP in blood still existed(P<0.05). The results of parameter-comparison among groups were more complicated. Further research is needed to clarify the mechanism whether local orthopedic forces influence the body metabolism.
